MAX LINDEMANN, OF EAST ST. LOUIS, ILLINOIS, ASSIGNOB OF ONE-HALF T0 EUGENE J. FEINER. 01? ST. LOUIS, MISSOURI.

DEGERMINATOB AND HULLER.

Application filed July 10, 1918.

To all whom it may concern:

Be it known that I, Max LINDEMANN, a citizen of the United States, and resident of East St. Louis, in the county of St. Clair and State of Illinois, have invented certaln new and useful Improvements in Degerminators and Hullers, of which the following is a specification, containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to degerminators and hullers, and has for its object, the provision of a pimple plate, which is attached at the discharge end of the ordinary degerminating and hulling roller. A further object is to increase the output of a degerminator and huller, and at the same time reduce the amount of power consumed.

In the drawings,

Figure 1 is a top view of my device with the cover thrown back.

Fig. 2 is a longitudinal vertical view with parts in section.

Fig. 3 is a plan view of the pimple plate.

Fig. 4 is a side view of the same.

Fig. 5 is a face view of the discharge end of the housing.

In the construction of my device I employ an ordinary degerminator 10 having a housing hinged in halves, as indicated by 11 and 12. In the portion 11 of the housing, I form an opening 13 through which the grain is fed to the interior of the housing. Within the housing is located a shaft 14 upon which is securely attached a degerminating roller 15; this roller being in the shape of a truncated cone.

This degerminating roller is provided with feed veins l6, and back of the feed veins, pimples or projections 17 are located; these pimples or projections being arranged in spiral form so as to feed the grain toward the discharge end and extend approximately to the center of the longitudinal axis of the degerminating roller. The rear portion of the degerminating roller is provided with pimples or projections 18, which are arranged at right angles to the horizontal axis of the degerminating roller. At the rear end of the roller I form a number of spiral grooves 19, the object of which is to feed the grain from the roller.

On the shaft 14 and abutting at the rear end of the roller 15 I secure my improved Specification of Letters Patent.

Serial No. 244,189.

device, which consists of a pimple plate 20, having a hub 21 by which it is secured to the shaft. The vertical surface of this plate 20 s provided with a series of pimples or proections 22, which act as additional degerminators and hull removers, and the periphery of the plate is provided with spiral feeding grooves 23, which feed the grain over the edge of the plate.

The rear end of the housing 26 is pro-- vided with a number of perforations 24, the object of which is to allow dust to escape from the device, and also act as an abrasive surface, and in the lower portion of this housing is hingedly attached a door 25, which is held in closed position by means of the lever 26, and the weight 27. The object of having this lever and weight is so that the pressure exerted on the inside of the machine, or in other words, the discharge of the grain may be regulated.

The operation of my device is as follows: The grain having been fed into the housing through the opening 13, is fed toward the spirally placed pimples 17 by means of the feeding wings or veins 16. The grain is then carried forward by the pimples 17, and comes in contact with the pimples 18. The constant supply of grain being fed forward forces the grain past the pimples 18 into the spiral grooves 19 on the roller and 28 on the pimple plate. The grain will then lodge between the pimples 22 and the rear perforated end 26 of the housing, and when a sufiicient amount of grain has lodged in this space, the door 25 will open and allow the degerminated and hulled grain to pass from the housing into a suitable receptacle.

By the use of my device, I have found that it is possible to speed the machine up to a much higher rate, accomplish more work, and with less power, than in the devices at present used, for the reason that in the devices of the present time, all of the degerminating and hull removing is done by the surface of the roller only; the rear end of the roller merely serving as a pocket, and performing no function whatever.

Having fully described my invention, what I claim is 1. A degerminator and huller comprising a housing, a shaft extending centrally therethrough, a tapered degerminating roller located within the housing and mounted on said shaft, a removable pimple plate mounted against the larger end of the degerminating roller and secured to said shaft, said pimple plate being provided on its face with a series of projecting pimples and on its periphery with feeding grooves, a perforated closure for the housing adjacent the pimple plate, a discharge opening formed in said perforated closure and a weight controlled door for closing said discharge opening.

2. A degerminator and huller comprising a housing with a perforated discharge end, a shaft extending centrally through said housing, a tapered degerminating roller mounted Within the housing and secured to said shaft, said tapered roller being provided on its ends with feed grooves, pimples formed on the roller intermediate the feed grooves, a removable pimple plate secured against the larger end of the degerminating roller and on said shaft, said removable pimple plate being provided on its face adjacent the perforated end with pimples and eoacting with the edges of the perforations for facilitating the degerminating and hulling of the grain, and provided on its periphery with feed grooves coinciding with the feed grooves formed on the large end of the degerminating roller. 7

In testimony whereof I have signed my name to thisspecification in the presence of two subscribing witnesses.

MAX LINDEMANN.
